1.How can an AND function be constructed from two NAND gate?

2.Use a truth table to show that P=(P+Q) or (P AND NOT Q).

There exist 4 boolean functions of a single variable and 16 functions of 2 variables. How many functions of 3 and 4 variables are there as well as n variable?

Sounds like cheating to me rather than a computer fault?

If u don't know leave it. May I remind u that this is a help room.
I hope this is now clear to u all nuts...

Bravo to those who understand this situation even though they can't help.

Those who can help I thank you in advance cheers.

However, I have found a solution to the 1st question so don't bother with it.
